    Auto merge of #104188 - jyn514:download-config-only, r=Mark-Simulacrum

    Make all download functions need only Config, not Builder

    This also adds a new `mod download` instead of scattering the download code across `config.rs` and `native.rs`.

    This is the simplest and also most bit-rotty part of https://github.com/rust-lang/rust/pull/102282. Opening it earlier so it's not mixed in with behavior changes and to avoid rebase hell.

    cc https://github.com/rust-lang/rust/issues/94829 (which nows has the hackmd linked).

    r? `@Mark-Simulacrum`
